FIG. 1 is a diagram showing a cross-sectional structure of a receiver 11 of the gas cooling device of the present invention. In the present gas cooling device, the receiver 3 of the system configuration of the conventional gas cooling device shown in FIG. 5 is replaced with the receiver 11 shown in FIG. 1, and a compressor (compressor) is used by using a refrigerant such as an alternative chlorofluorocarbon. 6. Skin condenser (condenser)
2, a vapor cycle cooling system including a receiver (liquid receiver) 11, an expansion valve 4, and an evaporator (evaporator) 5. The receiver 11 of the present apparatus includes a container of the receiver 11 containing the liquid refrigerant 10 and the gas refrigerant 9 therein, and an inlet pipe 15 for introducing the liquid refrigerant 10 from the skin condenser 2.
And an outlet pipe 12 for sending the liquid refrigerant 10 to the expansion valve 4, an outlet pipe 13, and a flexible joint 14 connecting the outlet pipe 12 and the outlet pipe 13. The outlet pipe 12 is connected to the distal end of the outlet pipe 13 fixed to the container of the receiver 11 via a flexible joint 14. Even if the receiver 11 is tilted, the flexible joint 14 allows the outlet pipe 12 to freely move under its own weight. Can change direction. When the aircraft tilts due to turning or the like, the liquid level of the liquid refrigerant 10 in the receiver 11 becomes a liquid level state determined by the centrifugal force and the force due to gravity. In response to this, the outlet pipe 12 is also constantly subjected to the liquid refrigerant 1 by centrifugal force and gravity.

The cold air of the outside air touches the outer plate 1 of the pod (pod) of the aircraft, and the cool air is transmitted from the pod outer plate 1 to the skin condenser 2. The high-temperature and high-pressure vapor-like refrigerant (Teflon substitute) compressed by the compressor 6 enters the skin condenser 2, where heat is taken from the surroundings and condensed into a liquid. The refrigerant that has become liquid flows into the tank of the receiver 11 and is stored at the bottom of the tank. In the tank of the receiver 11, the gaseous refrigerant 9 is located above and the liquid refrigerant 10 is located below.
Exists. In this state, when the aircraft tilts due to turning,
The liquid surface of the liquid refrigerant 10 in the receiver 11 has a liquid surface state determined by the centrifugal force and the force due to gravity. Accordingly, the outlet pipe 12 connected to the flexible joint 14 is always located in the liquid refrigerant 10 due to centrifugal force and gravity. Therefore, the liquid refrigerant 10 can be stably sent to the expansion valve 4 without being in a state where the gas refrigerant 9 is sent. Then, the liquid refrigerant 1 from the receiver 11
Numeral 0 is adiabatically expanded by the expansion valve 4 and becomes a low pressure, enters the evaporator coil of the evaporator 5, takes heat from the surroundings, and turns into steam. The refrigerant that has become vapor is supplied from the evaporator coil to the compressor 6.
Inhaled. Then it is compressed until it condenses. On the other hand, the cooling liquid for cooling the electronic device 8 by the evaporator 5 of the refrigeration cycle undergoes heat exchange, and the cooling liquid is circulated by the circulation pump 7 to cool the electronic device 8.

FIG. 4 shows a cross-sectional structure of another embodiment of the receiver 23 of the present gas cooling device. Two pipes are connected to the liquid refrigerant 10 in the container of the receiver 23, one of which is a pipe through which the refrigerant from the skin condenser 2 is introduced, and the other is a pipe which sends the liquid refrigerant 10 to the expansion valve 4. Then, the liquid refrigerant 10 is partitioned inside the receiver 23 using the bellows 22, and the bellows 22
The high-pressure gas 21 is put in the inside, and the liquid refrigerant 10 is pushed with a constant force so that the gas refrigerant 9 does not exist in the receiver 23.

定に保つことができる。The gas cooling device of the present invention is constructed as described above. When the aircraft is tilted by turning or the like, the liquid level of the liquid refrigerant in the receiver is determined by the centrifugal force and the force of gravity. State, and the outlet pipe in the receiver connected to the flexible joint is similarly located in the liquid refrigerant by centrifugal force and gravity, so that it does not enter a state in which a gaseous refrigerant is fed, and the expansion valve Liquid refrigerant can be stably fed into the apparatus. In addition, the liquid refrigerant is separated by a piston mechanism through an O-ring so that only the liquid refrigerant is contained in the receiver, and a mechanism that presses the liquid refrigerant with a predetermined pressure by a spring or a high-pressure gas is filled and pressed with a predetermined pressure. A mechanism or a bellows mechanism separates the liquid refrigerant, and a mechanism that seals the high-pressure gas in the bellows and holds it at a predetermined pressure is provided, so that the gas refrigerant cannot enter. Such a state does not occur, and the liquid refrigerant can be stably sent to the expansion valve. Therefore, even when the body is tilted, the cooling effect can be stably exhibited without the cooling capacity being reduced by the evaporator. Furthermore, even when the ambient temperature is low and the pressure inside the skin condenser is low, the liquid refrigerant in the receiver container is pushed out and stored in the skin condenser to reduce the heat exchange area and keep the pressure inside the skin condenser constant. Can be kept.
